Look at the section below to examine the graphic. The focal length of the lens affects the composition as well as magnification and FOV (field of view). The diameter of the aperture is a straight line distance from one side of the aperture to the other side, going through the center of the aperture. For example, f/2 and f/8 are common f-stop settings, where 2 and 8 are determined as the f-stop values, correspondingly. The shorthand “f” means f-stop like the “s” often stands after a shutter speed because it is measured in seconds. The number which underlies “f” indicates the f-stop value. F-stop is a dimensionless value, which is usually indicated by “f”. Many beginning photographers mistakenly think that aperture and f-stop are identical, which is wrong.Īperture means the diameter of the aperture through which the light hits the camera lens.į-stop (f-number or f-stop value) is focal length divided by the diameter of the aperture. Apart from basics, you will learn technical details which will give your shooting more confidence. I’ll try to explain everything you need to know about f-stop, focal length, focus range, and field of view in detail. Take a deep dive into the camera lens characteristics.
